My grandson gave me his only remaining chicken, a silverlaced Wyandotte I think but not sure. She was his only remaining because she cannibalised the other hens! She lays eggs daily and crows like a rooster. I put her in with my chickens but totally isolated her from everyone. They can see her and she can see them. My question is can her behavior change? He doesn’t want her to be destroyed but I don’t want her killing all my girls. There is a rooster in my coop so I wondered if that would make a difference in her behavior but don’t want any dead chickens to find out. Any advice is appreciated.
